Yeah the phillips, the t400's are the ue fitment so will probably be the same, they'll grip but it won't be snug like the original tips are.
I suppose some nail polish will work, anyway im happy with the stock buds for now.
Actually looking at that link, the olives look a tiny fraction smaller than the ue buds, must be worth a shot for what is an excellent bud anyway.
Well seems you can stretch em, ok i'll order a bunch.
Btw my phillips adore the p4, they are like a whole new iem all over again.
You got the Philips right? I know that Comply T-400 tips fit them, don't know about shure olives. Do those come in different sizes? The one I saw here seems too small in inner diameter. (compare with the T-400's inner diameter further down the page)
